following: * Bone lesions * Leptomeningeal disease * Ascites * Pleural/pericardial effusion * Inflammatory breast disease * Lymphangitis cutis/pulmonis * Abdominal masses that are not confirmed and followed by imaging techniques * Cystic lesions * Patients with HER-2/neu positive tumors, must have received prior treatment with trastuzumab (Herceptin®) or have a contraindication for trastuzumab * No evidence of active brain metastasis, including leptomeningeal involvement, on MRI or CT scan * CNS metastasis controlled by prior surgery and/or radiotherapy allowed * Must be asymptomatic for ≥ 2 months with no evidence of progression prior to study entry * Hormone receptor status not specified PATIENT CHARACTERISTICS: * Menopausal status not specified * Life expectancy ≥ 12 weeks * ECOG performance status 0-1 * ANC ≥ 1,500/mm³ * Platelet count ≥ 100,000/mm³ * Hemoglobin ≥ 9.0 g/dL * AST and ALT ≤ 2.5 times upper limit of normal (ULN) * Alkaline phosphatase ≤ 2.5 times ULN * Total bilirubin ≤ 1.5 times ULN * Creatinine ≤ 1.5 mg/dL * Urine protein:creatinine ratio \< 1 or urinalysis \< 1+ protein * Patients discovered to have ≥ 1+ proteinuria at baseline must demonstrate 24-hour urine protein \< 1 g * Not pregnant or nursing * Negative pregnancy test * Fertile patients must use effective contraception during and for 30 days after completion of study therapy * Able to complete questionnaires alone or with assistance * No peripheral neuropathy \> grade 1 * No history of allergy or hypersensitivity to albumin-bound paclitaxel, paclitaxel, gemcitabine hydrochloride, bevacizumab, albumin, drug product excipients, or chemically similar agents * No stage III or IV invasive, non-breast malignancy within the past 5 years * No other active malignancy, except nonmelanoma skin cancer or carcinoma in situ of the cervix * Patient must not be receiving other specific treatment for a prior malignancy * No uncontrolled hypertension (i.e., blood pressure \[BP\] \> 160/90 mm Hg on ≥ 2 occasions at least 5 minutes apart) * Patients who have recently started or adjusted antihypertensive medications are eligible providing that BP is \< 140/90 mm Hg on any new regimen for ≥ 3 different observations in ≥ 14 days * No bleeding diathesis or uncontrolled coagulopathy * No hemoptysis within the past 6 months * No prior arterial or venous thrombosis within the past 12 months * No history of cerebrovascular accident * No history of hypertensive crisis or hypertensive encephalopathy * No abdominal fistula or gastrointestinal perforation within the past 6 months * No serious non-healing wound, ulcer, or fracture * No clinically significant cardiac disease, defined as any of the following: * Congestive heart failure * Symptomatic coronary artery disease * Unstable angina * Cardiac arrhythmias not well controlled with medication * Myocardial infarction within the past 12 months * No comorbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for study entry or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens PRIOR CONCURRENT THERAPY: * See Disease Characteristics * No prior chemotherapy for metastatic disease * May have received one prior adjuvant chemotherapy regimen * Prior neoadjuvant chemotherapy allowed * More than 6 months since prior adjuvant or neoadjuvant taxane (i.e., docetaxel or paclitaxel) therapy * Prior hormonal therapy in either adjuvant or metastatic setting allowed * More than 4 weeks since prior radiotherapy (except if to a non-target lesion only, or single dose radiation for palliation) * Prior radiotherapy to a target lesion is allowed provided there has been clear progression of the lesion since radiotherapy was completed * More than 4 weeks since prior cytotoxic chemotherapeutic agent or investigational drug * More than 2 weeks since prior and no concurrent acetylsalicylic acid, anticoagulants, or thrombolytic agents (except for once-daily 81 mg acetylsalicylic acid) * More than 6 weeks since prior major surgery, chemotherapy, or immunologic therapy * More than 1 week since prior minor surgery (e.g., core biopsy) * Placement of a vascular access device within 7 days is allowed * More than 3 months since prior neurosurgery * No concurrent treatment in a different clinical study in which investigational procedures are performed or investigational therapies are administered * Trials related to symptom management (Cancer Control) which do not employ hormonal treatments or treatments that may block the path of the targeted agents used in this study may be allowed
